Constant Internet Outages

I don't think I've had a full week without any internet outages since I switched to Xfinity. Some are only a minute, but now they are getting longer. The most recent one has been over an hour now and seems like it has to do with upgrades which seem like they could've included an advanced warning. I want to talk to an actual human about the continuous issues but can't seem to find any way other than this forum to connect to a person. How do I talk to a person?
